Summary
Savannah River Pond 2, located in Martin, South Carolina, is a Federal-owned earth dam built in 1961 by the Department of Energy. This dam, also known as P Effluent Earth Dam, serves a primary purpose that is classified as "Other", with a maximum storage capacity of 138 acre-feet and a normal storage capacity of 48 acre-feet. The dam stands at a height of 23 feet and spans a length of 1050 feet, with a surface area of 30 acres and drainage area of 1.4 square miles.
The dam is situated along the Lower Three Runs-TR river or stream and is under the regulatory oversight of the Department of Energy. Despite its low hazard potential, the dam has not been inspected since January 2004, with a designated inspection frequency of 2 years. The condition assessment of the dam is currently listed as "Not Available", and information on emergency action plans, risk assessments, and inundation maps is also lacking. With its foundation on rock and no spillway or outlet gates specified, the D.O.E. Savannah River Pond 2 presents an intriguing case for water resource and climate enthusiasts to explore further.
In summary, D.O.E. Savannah River Pond 2 represents a unique earth dam structure in South Carolina, managed and regulated by the Department of Energy. With its historical significance dating back to 1961 and its location in the Barnwell county, this dam poses interesting questions regarding its current condition, inspection frequency, and emergency preparedness. Water resource and climate enthusiasts may find the data surrounding this dam to be a compelling starting point for deeper analysis and exploration into the intersection of infrastructure management, environmental protection, and climate resilience.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
